In a large bowl, add the cut vegetables. In a small bowl, stir together the olive oil, thyme, rosemary, garlic. Pour over the vegetables and stir to coat. Sprinkle parmesan cheese and pepper over the vegetables and toss again to coat.
Spread the coated vegetables out in a single layer on a large baking pan.
Bake for 35 - 45 minutes. Stir and flip the vegetables over after 20 minutes. Continue to cook until squash is fork tender. Salt vegetables to taste.
